Final answer:
The best evidence of Earth's rotation is provided by the observation of weather systems and ocean currents on a large scale, the apparent rotation of the night sky, and the precession of Earth's axis.
Step-by-step explanation:
The best evidence of Earth's rotation is provided by the observation of weather systems and ocean currents on a large scale. These systems rotate in different directions in the Northern and Southern Hemispheres, which is a direct result of Earth's rotation. For example, hurricanes in the Northern Hemisphere rotate counterclockwise, while those in the Southern Hemisphere rotate clockwise.
Another piece of evidence is the apparent rotation of the night sky. The rotation of the celestial sphere, which is caused by Earth's rotation, can be observed by the movement of stars throughout the night.
Lastly, the precession of Earth's axis is evidence of its rotation. Earth slowly precesses due to the torque of the Sun and the Moon on its nonspherical shape, resulting in a change in the position of the North Star over time.
